Saturn’s magnetic shield is asymmetrical compared to Earth’s, suggests a new study involving University College London (UCL) researchers, and this is likely a result of its fast rotation coupled with the heavy material it pulls around it.

Jason Heath had ventured with his family from northeastern Maine to the Sunshine State for a vacation—but soon found out they were set to “witness history” with the launch of NASA’s Artemis 2 mission.
After weeks of fuel leaks and other issues, NASA faced a trouble-free countdown Tuesday on the eve of astronauts’ first trip to the moon in more than half a century.
At 13:24:59 Central Standard Time on December 19, 1972, the Apollo 17 command module splashed down in the Pacific Ocean, about 350 nautical miles southeast of Samoa, concluding the last mission to the moon.
Eight CubeSats and one payload supported by the European Space Agency (ESA) have reached orbit, where they will demonstrate various applications aimed at improving how data is sent around and processed. Thanks to these demonstrations, practical and—sometimes—even life-saving data enabled from space will move more efficiently and reach the right actors on time in the future.
The ice giant Uranus is one of the most fascinating objects in the solar system, with its sideways rotation, intricate ring system, and unique family of moons. However, it is also one of the least explored objects in the solar system, owing to its extreme distance from the sun. With NASA’s Voyager 2 spacecraft remaining as the only spacecraft to visit Uranus, scientists continue to design and envision mission concepts for returning to explore Uranus and its icy secrets.
A Southwest Research Institute-led study found that protons and heavy ions react differently to solar magnetic reconnection events, revealing a more complex magnetic engine powering the solar wind. Magnetic reconnection converts magnetic energy into explosive kinetic energy, powering solar events and causing space weather that impacts Earth. Magnetic reconnection energizes protons and heavy ions, sending them shooting out from the sun at high speeds.
A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Technical University of Vienna (TU Wien) could soon pack the power of a laboratory-based spectrometer—an important workhorse tool for precision environmental gas analysis—onto a single microchip.
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew as it travels. This second form, known as orbital angular momentum, has attracted wide interest because it allows light to encode information, interact with matter in new ways, and probe physical and biological systems. Despite this promise, producing well-defined twisted light in free space remains technically challenging, especially when the light originates from small or localized sources.
While I was leading a tour of the National Air and Space Museum in January 2026, a visitor posed this insightful question: “Why has it taken so long to return to the moon?”
A Mississippi State physicist has produced a direct laboratory measurement of a key nuclear reaction believed to occur during explosive bursts on neutron stars. These bursts forge heavier elements—the building blocks of planets and life on Earth. The findings appear in The Astrophysical Journal.

Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers University graduate. Shea Cinquemani, who earned her bachelor’s degree from the School of Environmental and Biological Sciences in May 2025, has published a paper based on research she started during the spring of her senior year.
In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the universe. Understanding the structure of the atomic nucleus is crucial for research with implications for astrophysics and in applications such as medical imaging and data storage.
